William Shatner is facing a lawsuit from two former employees who allege that the "Star Trek" actor discriminated and harassed them after one of them refused to sign a waiver after getting injured on the job.

Oscar Alfaro and his wife, Delmy, filed a lawsuit in Los Angeles County Superior Court Tuesday, alleging that Shatner, 81, and his wife, Elizabeth, "harassed and berated" them so bad that they had to quit their jobs, according to court documents obtained by ABC News affiliate KABC-TV.

Shatner's manager and lawyer have not responded to ABCNews.com's requests for comment.

The Alfaros worked for Shatner for 20 years, but they left their unspecified jobs after Alfaro refused to sign a waiver after sustaining an undisclosed injury at the actor's Studio City, Calif., home, the lawsuit alleges.

As a result, the Alfaros claim they suffered humiliation, embarrassment and mental anguish in addition to the loss of earnings and benefits, according to the lawsuit. They're suing for an unspecified amount.
